Description

Technical Field

[0001] The present application relates to the field of air duct design, and in particular to a front air flow system of a vehicle and the vehicle. Background Art

[0002] New energy electric vehicles are vehicles powered by electricity and include battery packs, air conditioning systems, and some vehicles also include hybrid systems and other functional components. These components generate a large amount of heat during operation, which needs to be dissipated promptly. Therefore, a radiator assembly is usually installed inside the vehicle. The heat generated by the battery pack, hybrid system, and air conditioning system is exchanged with the outside air through the radiator assembly to dissipate the heat. Figure 1 , Figure 1 The specific structure of the front air intake duct in the prior art is shown in the figure. External air reaches the radiator assembly along the front air intake duct. The specific structure of the front air intake duct is as follows: a front air intake grille is opened under the front bumper, and a guide plate is installed between the air intake of the front air intake grille and the radiator assembly. The front end of the guide plate is sealed with the front air intake grille, and the rear end is sealed with the radiator assembly. In this way, after the external air enters from the air intake, it flows along the air intake duct surrounded by the guide plate to the radiator assembly.

[0003] Currently, the front grille is installed at a low position and the radiator assembly has a relatively large heat exchange area, so part of the deflector plate needs to extend upward from the air intake to a predetermined height before being sealed with the radiator assembly. Because the front end of the vehicle is also equipped with a front bumper beam and other structures, the deflector extends upward from the rear side of the front bumper beam, bypassing the front bumper beam. At the front bumper beam position, the deflector and the radiator assembly form a neck where the air intake channel size L is the smallest. The neck limits the amount of air flowing upward, such as Figure 1 The dashed line indicates the direction of airflow, and the neck size determines the air volume passing through the radiator assembly. In particular, the front bumper beam is closer to the air intake, where air velocity is higher. To prevent the deflector from collapsing and deforming toward the radiator assembly under high temperatures, a reinforcing rib structure is typically installed on the side of the deflector facing the front bumper beam. This further compresses the neck size L, which can severely result in an air intake volume that cannot meet the vehicle's cooling requirements.

[0004] Therefore, how to improve the structure of the air intake passage so that the air intake volume meets the heat dissipation requirements of the entire vehicle is a technical issue that has always been of concern to those skilled in the art. Utility Model Content

[0005] The purpose of the present application is to provide a front air flow system for a vehicle and a vehicle that can increase the total air intake volume for heat exchange with a heat dissipation component.

[0006] The present application provides a front airflow system for a vehicle, comprising:

[0007] front anti-collision beam;

[0008] Front grille assembly, with main frame for air intake;

[0009] The air guide has a peripheral wall that forms an air flow channel, the peripheral wall includes a front port portion and a rear port portion, and the rear port portion faces the heat dissipation component of the vehicle; the front port portion of the air guide is sealed and assembled with the main frame to form a gap, and the gap is at least partially located on the rear side of the front bumper beam. The front bumper beam seals the gap to form an air intake channel with the air guide and the main frame.

[0010] In the embodiment of the present application, the structure after the air guide and the main frame are assembled forms a gap on the rear side of the front bumper beam, and the gap can be sealed by the front bumper beam, that is, the front bumper beam, the air guide and the main frame form an air intake channel, and the air guide does not need to occupy the space between the front bumper beam and the heat dissipation component. Without changing the position of the front bumper beam, the width dimension L1 of the gas flow channel on the rear side of the front bumper beam is increased, and the amount of gas passing through this place is increased, thereby increasing the total amount of gas passing through the heat dissipation component. On the premise of meeting the heat dissipation requirements of the whole vehicle, the heat dissipation capacity of the whole vehicle can be improved.

[0011] In one example, the front port portion of the air guide member includes a first circumferential segment and a second circumferential segment, the second circumferential segment and the first circumferential segment are connected end to end to form an annular structure, the gap is formed between the first circumferential segment and the main frame, and the second circumferential segment is sealed and docked with the main frame at a corresponding position.

[0012] In one example, the top wall of the main frame has a supporting section, and the bottom wall of the front anti-collision beam is sealed against the outer surface of the supporting section.

[0013] In one example, the top wall has a bending section, the bending section is connected to a side of the supporting section facing the heat dissipation assembly, and the bending section is bent toward a side of the front anti-collision beam.

[0014] In one example, the front anti-collision beam includes a bottom wall, a connecting wall and a rear side wall connected in sequence, the bottom wall is sealed against the support section, and the connecting wall is inclined, and the connecting wall gradually inclines upward from the bottom wall to the rear side wall.

[0015] In one example, the first peripheral section and the front anti-collision beam, the second peripheral section and the main frame, and the main frame and the front anti-collision beam are sealed against each other by elastic sealing components, and all elastic sealing components are connected to form an integral structure.

[0016] In one example, the top wall of the main frame includes two extension walls, which are respectively located at both ends along the length direction of the main frame. The extension walls extend to the air guide member, and the connecting wall is sealed against the extension walls.

[0017] In one example, the first peripheral section is located on the rear side of the front anti-collision beam and on the top of the front anti-collision beam, and an elastic sealing component is pressed between the first peripheral section and the front anti-collision beam. The first peripheral section is sealed against the front anti-collision beam through the elastic sealing component.

[0018] In one example, the air guide has a convex portion protruding toward the front anti-collision beam, and the elastic sealing component is provided on the convex portion.

[0019] In one example, the air guide also includes a first shell section connected to the side of the protrusion away from the notch, and a first reinforcing rib is provided on the side of the first shell section facing the front bumper beam, and the first reinforcing rib is lower than the surface of the protrusion on which the elastic sealing component is installed.

Figure 5 The middle dashed line indicates the direction of airflow.

[0042] In the embodiment of the present application, the vehicle includes a power battery pack and an air-conditioning system, and may also include a heating system such as a hybrid system. A heat dissipation component 5 is further provided inside the vehicle for cooling the heating system in the vehicle. The heat dissipation component 5 may include one radiator, and of course may also include two or more radiators, and one radiator may cool one or several heating systems. This application shows a specific example in which the heat dissipation component 5 includes four radiators, specifically: a first radiator 51, a second radiator 52, a third radiator 53 and a fourth radiator 54. The shape and size of each radiator can be determined according to the heat exchange capacity of the corresponding heating system, and are not specifically limited herein.

[0043] The vehicle's front airflow system in the embodiments of this application is primarily used to direct external air toward the heat dissipation assembly 5, thereby forming an intake passage for air flowing from outside the vehicle to the heat dissipation assembly 5. The front airflow system comprises a front anti-collision beam 3, a front grille assembly 2, and an air guide 4. The front grille assembly 2 is located below the front anti-collision beam 3, and the air guide 4 is located behind the front grille assembly 2. It should be noted that this application defines the side facing the front of the vehicle as front, and the side facing the rear of the vehicle as rear, for simplicity of description of the technical solution.

[0044] The front anti-collision beam 3 in the embodiment of the present application can be a metal member, such as aluminum or steel. The front anti-collision beam 3 can be an aluminum extrusion that is simple to process and lightweight. The front anti-collision beam 3 can be fixed to the front longitudinal beam of the vehicle using mechanical fasteners such as bolts. Anti-collision blocks 32 can also be installed at both ends of the front anti-collision beam 3. The structure of the front anti-collision beam 3 can be determined according to the specific vehicle model.

[0045] In the embodiment of the present application, the vehicle further comprises a front secondary anti-collision beam 6 and a front bumper 1. The front secondary anti-collision beam 6 is located below the front grille assembly 2. The front bumper 1 is located in front of the front anti-collision beam 3. The structures of the front bumper 1 and the front secondary anti-collision beam 6 can be determined according to the specific vehicle model and are not specifically limited herein.

[0046] In the embodiment of the present application, the front grille assembly 2 includes a main frame 21, and the main frame 21 forms an air inlet. A grille 22 can be set in the air inlet to divide the air inlet into multiple air inlet gaps. Of course, the grille 22 can also be rotatably connected to the main frame 21, and the size of the air inlet gap and the air inlet direction can be adjusted by adjusting the posture of the grille. Of course, the grille can also be fixedly connected to the main frame 21, and the air inlet gap remains unchanged. The front grille assembly 2 can be fixed to the front anti-collision beam 3 and the front auxiliary anti-collision beam 6 by bolts and other components. Figure 7 It is shown that a mounting plate 23 is provided on the top of the front grille assembly 2 , and mounting holes for bolts or screws are provided on the mounting plate 23 .

[0047] The air guide 4 in the embodiment of the present application has a peripheral wall that forms an air flow channel. The peripheral wall has a front port portion 42 and a rear port portion 41. The rear port portion 41 faces the heat dissipation component 5 of the vehicle and can be sealed and connected to the outer frame of the heat dissipation component 5. The two can be sealed and connected by an elastic seal. The elastic seal can be a sealing gasket or a sealant. The rear port portion 41 can be positioned with the outer frame by a locating pin and fixedly connected to the outer frame by bolts, screws and other components. After the front port portion 42 of the air guide 4 is sealed and assembled with the main frame 21, a gap is formed. The gap is at least partially located on the rear side of the front anti-collision beam 3. That is, there is no air guide 4 or main frame 21 in at least a part of the area between the front anti-collision beam 3 and the heat dissipation component 5. The front anti-collision beam 3 in the present application seals the gap, so that the front anti-collision beam 3, the air guide 4 and the main frame 21 form an air intake channel.

[0048] From the above description, it can be seen that in the embodiment of the present application, the structure after the air guide 4 and the main frame 21 are assembled forms a gap on the rear side of the front anti-collision beam 3, and the gap can be sealed by the front anti-collision beam 3, that is, the front anti-collision beam 3, the air guide 4 and the main frame 21 form an air intake channel, and the air guide 4 does not need to occupy the space between the front anti-collision beam 3 and the heat dissipation component 5. Without changing the position of the front anti-collision beam 3, the width dimension L1 of the gas circulation channel on the rear side of the front anti-collision beam 3 is increased, the amount of gas passing through this place is increased, and the total amount of gas passing through the heat dissipation component 5 is increased. On the premise of meeting the heat dissipation requirements of the whole vehicle, the heat dissipation capacity of the whole vehicle can be improved.

[0049] In a specific embodiment, the air intake passage L1 formed by the front anti-collision beam 3, the air guide 4 and the main frame 21 is about 15 mm larger than L in the prior art.

[0050] In one specific embodiment, the front end portion 42 of the air guide 4 includes a first peripheral segment and a second peripheral segment, which are connected end to end. The first peripheral segment is located on the rear side of the front anti-collision beam 3, forming a gap between the first peripheral segment and the main frame 21, and the second peripheral segment is sealed and connected to the main frame 21 at a corresponding position. Specifically, the main frame 21 has a flange 211 on the side facing the air guide, and the second peripheral segment 21 is sealed to the flange 211. In other words, the front end portion 42 of the air guide 4 is an annular structure, the front end surface of which is partially sealed with the front anti-collision beam 3, and the other portion is sealed with the main frame 21.

[0051] In this embodiment, the air guide member 4 has a relatively simple structure and is easy to process.

[0052] In the embodiment of the present application, the top wall of the main frame 21 has a support section 210, and the bottom wall 32 of the front anti-collision beam 3 is sealed against the outer sidewall of the support section 210. In this embodiment, the bottom wall 32 of the front anti-collision beam 3 can be sealed against the outer sidewall of the support section 210 via an elastic sealing component 7. In this embodiment, the bottom wall 32 of the front anti-collision beam 3 is directly sealed against the outer surface of the top wall of the main frame 21, which facilitates assembly. The front anti-collision beam 3 can also be pressed against the top wall of the main frame 21 under the action of its own weight, resulting in a relatively good sealing effect.

[0053] The front anti-collision beam 3 is sealed against the top wall of the main frame 21. The main frame 21 needs to have a certain strength. In order to meet the strength requirements of the main frame 21, in the embodiment of the present application, the top wall also has a bending section 212. The bending section 212 is connected to the side of the support section 210 facing the heat dissipation component 5, and the bending section 212 is bent toward the side of the front anti-collision beam 3. The bending section 212 increases the use strength of the main frame 21 to a certain extent, and the weight of the main frame 21 is also relatively light.

[0054] In order to minimize the impact of the front anti-collision beam 3 on the flow of air in the air intake passage, in the embodiment of the present application, the structure of the front anti-collision beam 3 can be configured as follows: the front anti-collision beam 3 includes a bottom wall 32, a connecting wall 31, and a rear side wall 33 connected in sequence. The bottom wall 32 is sealed against the support section 210, and the connecting wall 31 is inclined. From the bottom wall 32 to the rear side wall 33, the connecting wall 31 gradually tilts upward. In other words, the connecting wall 31 is arranged along the direction of airflow. The connecting wall 31 can guide the flow of airflow and reduce the resistance to airflow. The inclined setting of the connecting wall 31 can also provide space for the bent section 212 of the main frame 21. In particular, the connecting wall 31 can form a flow-guiding structure with the air guide 4 and the main frame 21 to further reduce the airflow resistance.

[0055] In one specific embodiment, the top wall of the main frame 21 further includes two extension walls 24, one located at each end along the length of the main frame 21. The extension walls 24 extend to the air guide 4, and the connecting wall 31 seals against the extension walls 24. The extension walls 24 can also be tilted to match the seal with the connecting wall 31. The connecting wall 31 and the extension wall 24 can be elastically sealed against each other via a third elastic sealing member 7.

[0056] In the above embodiment, by providing two extension walls on the top wall of the main frame 21, the gap can be sealed on both sides along the length, which has a simple structure and is easy to implement.

[0057] In the embodiment of the present application, the first peripheral section is located at the rear side of the front anti-collision beam 3. Specifically, the front end surface of the first peripheral section abuts against the rear side wall 33 of the front anti-collision beam 3. In order not to occupy the rear side space of the front anti-collision beam 3 as much as possible, the sealing connection position between the guide member and the front anti-collision beam 3 can be as close to the top of the front anti-collision beam 3 as possible, that is, the guide member can be considered to be located at the top of the rear side wall 33 of the front anti-collision beam 3. Usually, the guide member is a shell structure, and its material is a rigid material, such as aluminum or steel. In order to avoid direct contact and wear between the guide member and the front anti-collision beam 3 and to improve the sealing between the two, an elastic sealing component 7 is pressed between the first peripheral section and the front anti-collision beam 3, and the first peripheral section is sealed against the front anti-collision beam 3 through the elastic sealing component 7.

[0058] In the embodiment of the present application, the air guide 4 has a protrusion 43 that projects toward the front anti-collision beam 3, and the elastic sealing member 7 is disposed on the protrusion 43. The local protrusion of the air guide 4 enhances the strength of the air guide 4 at that location. In other words, the protrusion 43 strengthens the air guide 4 to a certain extent, which helps to improve the sealing reliability between the air guide 4 and the front anti-collision beam 3. The height and width of the protrusion 43 along the airflow direction can be determined according to actual conditions and are not limited herein.

[0059] The closer to the air inlet of the front grille assembly 2, the greater the airflow velocity, and correspondingly the lower the air pressure, the more likely the outer wall of the air passage will collapse toward the heat dissipation assembly 5. As mentioned above, the guide member is a shell structure with a relatively thin thickness. In order to prevent the guide member from local collapse and deformation in a high temperature environment, the present application also adopts the following configuration.

[0060] In this embodiment, the air deflector 4 further includes a first housing segment 47 connected to the side of the protrusion 43 facing away from the notch. A first reinforcing rib 44 is provided on the side of the first housing segment 47 facing the front bumper beam 3. The first reinforcing rib 44 is lower than the surface of the protrusion 43 where the elastic sealing member 7 is mounted. The first reinforcing rib 44 can have various configurations, such as vertical ribs or raised dots. The figure illustrates a combination of vertical ribs and raised dots.

[0061] Correspondingly, a second reinforcing rib 45 can be further provided on the air guide 4. The second reinforcing rib 45 is located at the bottom of the air guide 4 and close to the front grille assembly to prevent the guide 4 from locally collapsing and deforming at this position in a high temperature environment.

[0062] In the embodiment of the present application, elastic sealing components 7 are used to seal against each other between the first perimeter segment and the front anti-collision beam 3, between the second perimeter segment and the main frame 21, and between the main frame 21 and the front anti-collision beam 3. All elastic sealing components are connected to form an integral structure, thereby improving sealing reliability, effectively preventing hot air backflow, and improving the heat dissipation capacity of the entire vehicle. Each elastic sealing component 7 can be a sealing gasket, which is easy to install and has high sealing reliability. The sealing gasket can be a component such as foam or rubber. Of course, the elastic sealing component 7 can also be other sealing components, such as sealant.

[0063] Compared with the protrusion 43 , the front surface of the first housing segment 47 is recessed toward the heat dissipation assembly 5 .

[0064] If there is ample space above the front bumper beam 3, the air guide 4 can be positioned as far away from the heat dissipation assembly 5 as possible to increase air capacity, allowing airflow to flow through the heat dissipation assembly 5 more effectively, thereby improving the heat dissipation effect of the heat dissipation assembly 5. In the embodiment of the present application, the air guide 4 also includes a second housing segment 46. The second housing segment 46 is connected to the side of the first housing segment 47 away from the protrusion 43. The second housing segment 46 partially protrudes toward the front bumper beam 3 relative to the first housing segment 47, so as to be positioned above the front bumper beam 3.

[0065] The vehicle provided in the embodiment of the present application includes the front air flow system of the above-mentioned vehicle, and therefore also has the above-mentioned technical effects of the front air flow system of the vehicle.
